This contains the format for an Arcana save file. Each file takes up $500 bytes, and has a copy for protection.
They are tranferred 8 bytes at a time via MVN at $00/CAB6, which uses X= RAM address, Y= SRAM address, A= # bytes to copy
The file is saved twice and a ton of checksums are written by looping through the data at least 20 times.
